My initial impressioms of the DevTerm A06

Playing youtube is fine. To clarify:

  • Video playback from youtube works, generally speaking
  • I recorded a video using my phone of the playback. I intended on attaching it here to show that it works, but was unable to
  • Instead I copied that video over to the DevTerm A06 and tried to play it. It’s a 4k HEVC (x265) video, so VLC only played a few frames of it
  • I then used ffmpeg to convert that 4k x265 video to 720 x264. That took 8 and 1/4th minutes to complete.
  • The playback of the 720p video in VLC was stuttery, but did manage to play

However, the above testing was affected by the fact that cores 5 & 6 (the high performance cores) were disabled.

I’ve since enabled those cores.

  • Converting the 10-second 4K video to 720 took 2.5 minutes (down from 8.25) to complete
  • Playback of the 720p video in VLC works great now
  • Oddly enough playback of the 4K video in VLC is worse after enabling the high performance cores.

It seems that ffmpeg/VLC on this system doesn’t utilise the GPU for video playback? Is this the case?
